10 Best Mini Split Ac Unit For Semi Truck 2025 in the United States

The Mieligo 12V Truck Air Conditioner offers 10,000 BTU cooling power, which is solid for providing comfortable temperatures inside semi-truck cabs and similar vehicles. It uses a DC inverter compressor, which is good for quickly adjusting cooling output and maintaining energy efficiency, helping to save power during use. The system is a split type with separate indoor and outdoor units, making it easier to install in trucks, trailers, and even equipment like cranes or RVs. It runs quietly at about 45 decibels, so it won’t add much noise to your cab environment. The brushless fan improves durability and keeps the noise low, which is helpful during long trips or parking.

A copper evaporator inside ensures efficient cooling, although this part can add to the cost. The unit comes pre-charged with refrigerant, which simplifies installation and avoids extra hassle or expense. You also get remote and panel controls for easy operation, plus an air filter to keep the air inside clean. The system weighs around 70 pounds, which is manageable for installation by professionals. For those concerned about moisture, the unit also helps with dehumidification, keeping the cab comfortable and less sticky.

This 12V Mini Split Air Conditioner is tailored for semi-truck drivers who want efficient cooling while on the road. With a cooling capacity of 10,000 BTU, it’s strong enough to quickly lower the temperature inside large vehicle sleepers or cabins, thanks to its powerful 20CC scroll compressor that cools rapidly within about 8 minutes. The variable frequency inverter feature helps reduce energy use by adjusting cooling power based on the surrounding heat, which can save fuel or battery life—a definite plus for long hauls. It runs on 12 volts and includes protections to prevent battery drain, ensuring your truck starts without issues.

Noise is kept relatively low at 65 dB, similar to background music or a normal conversation, which is acceptable though not ultra-quiet.
